Understand the key differences between Design & Build and the traditional build-only approach — and how to choose the right procurement method for your landed home project in Singapore.
What is Design & Build (D&B)?
Under a Design & Build approach, the homeowner engages a single contractor who manages:
- Design (in-house or through appointed architects)
- Authority submissions (URA, BCA, etc.)
- Construction works
This provides homeowners with a single main point of contact throughout the project.
What is Build-Only (Architect + Tender)?
Under the build-only approach:
- The homeowner appoints an architect or consultant first
- The architect develops the design
- The project is put out for tender
- Contractors submit quotations
- One contractor is appointed to carry out the construction works
Under this arrangement, the design and construction responsibilities are handled by separate parties.
Key Comparison
| Design & Build | Build-Only | |
|---|---|---|
| Timeline | Design and construction planning can overlap — generally shorter overall project duration | Sequential process (Design → Tender → Build) — tender stage alone may take approximately 1–3 months |
| Cost | Costs are considered during the design stage — more practical and buildable solutions | Final tender price may exceed the initial budget — redesign or cost-cutting may be required after tender |
| Point of Contact | Single point of contact with the contractor — easier coordination and communication | Separate coordination with architect and contractor |
| Design Flexibility | Practical and cost-efficient designs — may have limitations depending on the contractor's design approach | Greater design independence — suitable for highly customised or architect-driven homes |
Which Should You Choose?
Design & Build may be more suitable if you:
- Prefer a faster project timeline
- Want a single point of contact
- Prioritise better coordination and cost control
Build-Only may be more suitable if you:
- Prioritise unique architectural design
- Prefer independent design oversight
- Are comfortable coordinating between multiple parties
Conclusion
Both Design & Build and the traditional build-only method can deliver successful projects when managed properly.
Ultimately, the most suitable approach depends on the homeowner's priorities — whether in terms of timeline, budget control, design flexibility, or preferred level of involvement throughout the project. Understanding these differences will help you choose the approach that best suits your project goals and requirements.
